Thats bizarre... A Belgium university lecturer has infuriated his students by throwing out 700 exam papers with the rubbish.Hugo Schouppe, who teaches at the Lessius High School, in Antwerp, had taken the psychology papers home to mark.A cleaner then found the pile of papers on his desk and, mistaking them for waste, threw them away.Schouppe told the Antwerp Gazette newspaper: "I regret it from the bottom of my heart.The students have all been told they must take the exam again.One angry pupil said: "They made an error and we have to pay for it. It's a scandal."
